To a/ZZ whom it may concern,.-

Beit known that I, CHARLES CLUTHE, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and Improved Hernia- Truss, of which the following is a specification.

The object of the invention is to provide a hernia truss in which the pad will remain in the proper position without regard to thel movement or position of the body and which will automatically increase the pressure on the hernia immediately upon the wearer coughing or otherwise acting so as to jar upon or distend the abdomen, and it consists in the peculiar construction, arrangement and combinations of parts hereinafter more particularly described and then definitely claimed.

Figure 1, is a perspective view of my improved hernia truss attached toits belt. Fig. 2, is an enlarged perspective detail without its belt. Fig. 3, is a detail of the hernia pad connected to its spindle. tive view of an alternative form of my improved hernia truss. Fig. 5, is a sectional view of the pad.

In the drawings, A is a plate made of hard unyielding material, such as metal. The surface a, of this plate is slightly concave so that when the plate is pressed against a soft portion of the body, a partial vacuum will be formed sufficient to hold the plate in position. The center of the plate A, is cupped to receive the hernia pad B, this pad, being connected by a iexible joint, such as a ball and socket-joint, to a spindle C, which passes through the center of the cupped portion of the plate A, and has a head formed on it to prevent the said spindle getting out of position.

H, is a spring located between the pad B, and the belt A, so as to impart an elastic pressure against the hernia.

D, is a body belt which I prefer to make of raw-hide or other suitable water-proof material. One end of this belt is connected to the plate A, as indicated, and the other end of the belt has an elastic section E, inserted in it and forming a connection between the plate A, and the belt.

F, is a bar connected at one end to the back of the plate A, and extending over the spindle C, which plate is connected to a non- Fig. 4, is a perspecelastic strip G, which extends and is fastened to the non-elastic portion of the belt D. Owing to this connection, it follows that in the event of any sudden expansion of .the elastic section E, in the belt D, which elastic section causes the non-elastic strip G, to draw upon the spring plate F, which by acting against the end of the spindle C, forces the pad B, against the hernia, thereby automatically increasing the pressure against the hernia instantaneouslyupon any strain occurring which might otherwise disturb the hernia.

In Fig. 4, an alternative form of truss is shown in which the back is provided with a hinged cover I, to which the belt is connected instead of directly to the plate A. A slot is provided in the cover I, through which the bar F, plays.

Fig. 5, is a sectional View of the pad B. This pad consists of a rubber vessel havinga thick or stiffened back b fitted into a flanged metal plate H, fixed to the end of the spindle C, as indicated.

d, is a tube through which the water is pumped into the pad B, the body of which is of exible rubber and is therefore expanded by the water pressure, assuming the form indicated in Fig. 5, which is formed in wconnection with the flange on the plate H, 'and forms a lock holding the pad in position, at the same time bulging out the pad so that it will be smooth and not stretch as will be understood on reference to Fig. 5.

What I claim as my invention isl. In a hernia truss, a cupped plate connected to a body belt made of non-elastic material having an elastic section inserted in it, a hernia pad iiexibly connected to a spindle extending through the said plate, a bar connected to the plate and extending over the said spindle, in combination with a non-elastic strip arranged to connect the bar to the non-elastic portion of the belt, substantially as and for the purpose specified.

2. In a hernia truss, a cupped plate having a slightly concave surface surrounding the cup and connected to a body belt made of non-elastic material having an elastic section inserted in it, a hernia pad flexibly connected to a spindle extending through the said plate, a spring inserted between the pad and plate, a bar connected to the plate and extending IOO over the said spindle, in combination with a tograsp and hold said rubber vessel'when Io non-elastic strip arranged to connect the bar the letter is expanded, substantially as deto themen-elastic portion of the belt, substanscribed. tial] y as and for the purpose specified.
